参考答案:
B
本题详细解析:
Explanation:
The electric field vector inside a hollow conductor is zero. Due to the lack of field inside the sphere, the electric potential is constant and equal to the surface value .
Outward from the surface of the sphere, the electric field varies with the inverse‾inverse square of the distance from the center while electric potential decreases inversely with the distance from the center.
